Poly Blackwire 3320 Headset, Black

The Poly Blackwire 3320 is a stereo headset designed for professional use in office or call center environments. It connects directly to a computer via a wired USB-A interface, providing a stable connection for communication applications. The on-ear, closed-back design incorporates 32 mm dynamic drivers that cover a frequency range of 20 Hz to 20,000 Hz. Its construction prioritizes comfort for extended wear, featuring a lightweight, adjustable headband and cushioned earpads.

For vocal clarity, the headset is equipped with a noise-canceling boom microphone, which is designed to reduce the pickup of ambient background sound. The microphone is attached to a flexible boom that can be folded away when not in use. Audio quality is further refined by integrated Digital Signal Processing (DSP). For user convenience, the cable includes an in-line control unit for adjusting volume, muting the microphone, and managing calls without needing to use software controls.
